Find ASCII Value of a Character in C++

There are 128 characters in the ASCII (American Standard Code for Information Interchange) table with values ranging from 0 to 127.

Some of the ASCII values of different characters are as follows −

A program that finds the ASCII value of a character is given as follows −

Example

 Live Demo

#include <iostream>
using namespace std;
void printASCII(char c) {
   int i = c;
   cout<<"The ASCII value of "<<c<<" is "<<i<<endl;
}
int main() {
   printASCII('A');
   printASCII('a');
   printASCII('Z');
   printASCII('z');
   printASCII('$');
   printASCII('&');
   printASCII('?');
   return 0;
}

Output

The ASCII value of A is 65
The ASCII value of a is 97
The ASCII value of Z is 90
The ASCII value of z is 122
The ASCII value of $ is 36
The ASCII value of & is 38
The ASCII value of ? is 63

In the above program, the function printASCII() prints the ASCII values of characters. This function defines an int variable i and the value of the character c is stored into this variable. Since i is integer type, the corresponding ASCII code of the character is stored into i. Then the values of c and i are displayed.

This is demonstrated by the following code snippet.

void printASCII(char c) {
   int i = c;
   cout<<"The ASCII value of "<<c<<" is "<<i<<endl;
}
